Method and apparatus for a compact programming block for a hearing assistance device, such as a hearing aid. In one embodiment, the compact programming block is formed in a programming block module with another component. In various embodiments the programming block module includes a flexible circuit design. In various embodiments, the design incorporates a first flexible circuit disposed in a programming module that receives a second flexible circuit connection. In various embodiments, the programming block module includes a plurality of contact springs. In various embodiments, the programming block module is shaped to provide a small profile that is integrated with a microphone housing. In such embodiments, the integrated microphone and programming block module can be used in a hearing assistance device. In various embodiments, the programming block is integrated with a pushbutton. In such embodiments, the integrated pushbutton and programming block can be used in a hearing assistance device. Combinations of these various aspects can be provided according to various embodiments of the present subject matter.

FIG. 1 is a perspective view of a module 100 with integrated programming block and microphone, according to one embodiment of the present subject matter. FIG. 1 shows a main housing 140 that connects to a cover 150 to enclose the microphone (not shown) and the connector assembly using flexible circuit 160. In various embodiments, the main housing 140 includes a hole 110 for sound to reach the microphone. In various embodiments the housing 140 and cover 150 form a slit opening 120 to receive a tape connector (not shown) for the programming connection. It is understood that other shapes for connection can be used without departing from the scope of the present subject matter. Thus, slit opening 120 can be in different configurations for different connectors.

In various embodiments, the flexible circuit 160 has contacts 130 for connections to the programming connector. The housing has microphone connections that are more visible in FIG. 2. In various embodiments, the main housing is a welded frame. Different main housing materials may be used to provide a rigid module housing. In various embodiments, the main housing is made out of metal. In various embodiments, the main housing is made out of an electrically insulating material. In various embodiments, the housing is a 0.2 mm frame. In various embodiments the frame is a laser welded frame. In various embodiments, the cover 150 is made of a conductive material. In one embodiment, the cover 150 is an electrically insulating material. In various embodiments, the cover 150 is made out of FR4. Other sizes and materials and assemblies may be used without departing from the scope of the present subject matter.

FIG. 2 is an exploded view of the module 100 of FIG. 1, according to one embodiment of the present subject matter. This exploded view shows one embodiment where an elastomeric pad 280 is sandwiched between the cover 150 and flexible circuit 160 to urge connector contacts 290 slightly outward to provide a better connection with a flexible tape connector (not shown) as it is inserted. A flexible tape connector inserted into slit 120 will contact the plurality of contacts 290 as it is inserted between the flexible circuit 160 and bias element 300. The bias element provides a plane for contacts between a flexible tape connector (not shown) and the flexible circuit 160. Thus, the opening is ramped using the elastomeric pad to make more robust connections. In various embodiments, bias element 300 is optional and can be omitted provided that the geometries of the microphone inserted into the main housing 140 can provide a suitable surface to bias against a connector inserted into slit 120. Other variations and component configurations are possible without departing from the scope of the present subject matter.

In various embodiments the main housing 140 is metallic. In such embodiments, a number of insulated contact feedthroughs can be used to provide signal and power contacts 270 for the component or components in the module (for example, a microphone). In the embodiment shown in FIG. 2 a plurality of microphone connections 270 are provided for electrical connections with the microphone (not shown) that is enclosed in the main housing 140 when assembled.

FIG. 3 is a perspective view of a module 310 with integrated programming block and microphone using spring contacts 320, according to one embodiment of the present subject matter. The cover 350 has openings to accommodate the spring contacts 320 and provide freedom of movement of the spring contacts 320. The design can be made similar to that of FIG. 2, and does not require a flexible circuit 160 for its design. In various embodiments, the spring contacts 320 can extend towards the bottom of FIG. 3 to provide contacts for electrical connections for the programming connector.

The present programming block can be integrated with other components. In various embodiments, a pushbutton is integrated with the programming block as a module. In such embodiments, the module includes the programming block and the pushbutton. Other components can be integrated with the programming block. In various embodiments it is advantageous to combine the programming block with other devices such that the increase in size and volume for the combined module is relatively small. For example, with one microphone and programming block combination, the added dimensions arising from integrating the programming block over a microphone dimension is about 0.4 mm of width and 1.4 mm of thickness added to the microphone dimensions. That is a relatively modest increase in volume and very efficient over other programming blocks which can add over twice that amount of size and/or volume.

Although various embodiments demonstrate the present programming module with 4 programming connections and 3 microphone connections, it is understood that the actual amount of connections may vary without departing from the present subject matter. The actual connections may vary with different components and with different signal and power lines to handle. Furthermore, even though the present subject matter is described in light of a programming connection, it is understood that the present subject matter can be used for other purposes, including, but not limited to, streaming audio, two way communications, and diagnostic purposes.

In various embodiments the programming block is adapted to receive a pushbutton module. In various embodiments, a removable pushbutton module approach provides a programming block that is adapted to receive the removable pushbutton module for pushbutton operation. When the pushbutton module is removed, a snap in programming cable can be placed into the vacant connector block that had previously accommodated the pushbutton module. Thus, with the pushbutton module removed, the vacancy is the programming connector block. When programming is complete, the programming cable is removed and the pushbutton module is inserted. In various embodiments, the leads of the programming connector can be used for the pushbutton function. Some designs may short multiple leads to provide a switching function. When the switch is depressed, it shorts leads which are sensed by the electronics of the device for the pushbutton function.

Some benefits include increased savings in volume of such devices, reduced touch points, reduced part count, and stronger shell designs for devices.

The present subject matter is demonstrated for hearing assistance devices, including hearing aids, including but not limited to, behind-the-ear (BTE), in-the-ear (ITE), in-the-canal (ITC), receiver-in-canal (RIC), or completely-in-the-canal (CIC) type hearing aids. It is understood that behind-the-ear type hearing aids may include devices that reside substantially behind the ear or over the ear. Such devices may include hearing aids with receivers associated with the electronics portion of the behind-the-ear device, or hearing aids of the type having receivers in the ear canal of the user, including but not limited to receiver-in-canal (RIC) or receiver-in-the-ear (RITE) designs. The present subject matter can also be used in hearing assistance devices generally, such as cochlear implant type hearing devices and such as deep insertion devices having a transducer, such as a receiver or microphone, whether custom fitted, standard, open fitted or occlusive fitted. It is understood that other hearing assistance devices not expressly stated herein may be used in conjunction with the present subject matter.

This application is intended to cover adaptations or variations of the present subject matter. It is to be understood that the above description is intended to be illustrative, and not restrictive. The scope of the present subject matter should be determined with reference to the appended claims, along with the full scope of legal equivalents to which such claims are entitled.
